5G Waveform Generator

Create, impair, visualize, and export 5G NR waveforms

Description

The 5G Waveform Generator app enables you to create, impair, visualize, and export 5G NR waveforms.

The app provides these capabilities by using the Wireless Waveform Generator app configured for 5G NR waveform generation. Using the app, you can:

• Generate NR test models (NR-TM) for FR1, as defined in TS 38.141-1 Section 4.9.2 [1].

• Generate NR-TM for FR2, as defined in TS 38.141-2 Section 4.9.2 [2].

• Generate NR downlink fixed reference channel (FRC) waveforms, as defined in TS 38.101-1 Annex A.3 [3].

• Generate NR uplink FRC waveforms, as defined in TS 38.104 Annex A [4].

• Export the NR waveform to your workspace as a structure to a .mat or a .bb file.

• Distort the NR waveform by adding RF impairments, such as AWGN, phase offset, frequency offset, DC offset, IQ imbalance, and memoryless cubic nonlinearity.

• Visualize the NR waveform in spectrum analyzer and OFDM grid.

• Generate an NR waveform that you can transmit using a connected lab test instrument. The app can transmit a waveform by using instruments supported by the rfsiggen (Instrument Control Toolbox) function. Use of the transmit feature in the app requires Instrument Control Toolbox™ software. For more information, see the documentation for Instrument Control Toolbox.

To create, impair, visualize, and export waveforms other than NR waveforms, you must reconfigure the app. For a full list of features, see the Wireless Waveform Generator app.

Open the 5G Waveform Generator App

MATLAB^® Toolstrip: On the Apps tab, under Signal Processing and Communications, click the app icon.

MATLAB Command Prompt: Enter nrWaveformGenerator. This command opens the Wireless Waveform Generator app configured for 5G waveform generation.

Examples

App-Based 5G NR-TM and FRC Waveform Generation

This example shows how to use the 5G Waveform Generator app to generate NR test models (NR-TM) and NR uplink and downlink fixed reference channel (FRC) waveforms.

Open 5G Waveform Generator App

On the Apps tab of the MATLAB® toolstrip, under Signal Processing and Communications, click the 5G Waveform Generator app icon. This app opens the Wireless Waveform Generator app configured for 5G waveform generation.

Select 5G NR Waveform

In the Waveform Type section on the app toolstrip, click the waveform you want to generate. You can select any of these waveforms.

• 5G Downlink FRC

• 5G Uplink FRC

• 5G Test Models

Generate 5G NR Waveform

In the left pane of the app, on the Waveform tab, you can set the parameters of the selected waveform. On the app toolstrip, in the Generation section, you can add impairments and set visualization tools. To visualize the waveform, click Generate. You can export the generated waveform to the MATLAB workspace as a structure in a .mat or .bb file.

For example, this picture shows the visualization results of a downlink FRC waveform using default parameters.

Transmit 5G NR Waveform

This feature requires Instrument Control Toolbox. To transmit the generated waveform, on the app toolstrip, click on the Transmitter tab and set up the instruments. You can use all the instruments supported by the rfsiggen (Instrument Control Toolbox) function.
